Sirius Pictures Gallery Feb 17th 2012, 11:06 Sirius, also known as the Dog Star, is the brightest star in the sky. Its name comes from the Greek word for scorching. At 8.7 light years, it is also one of the closest stars to our own sun. In 1844, F.W. Bessel used analysis of its motion to determine that it had a companion. This companion was confirmed by observations in 1862 and is now known to be a white dwarf. Sirius B, the companion, has received considerable attention itself, since it is the first white dwarf with a spectrum to show a gravitational red shift as predicted by the general theory of relativity. Sirius is located int the constellation Canis Major.
